On Zorin OS Lite, clipboard history is managed by ClipMan, which comes by default with the XFCE desktop.
Cinnamon desktop also comes with a clipboard manager. I was a little bit (But only a little bit) surprised to learn today that Gnome comes with No Clipboard Manager at all. Gnome touts atself as being professional and for developers, after-all. So, I figured this most basic of all features must be included.
Nope.
Gnome...
